Temperature Logger : Guide 2025

Temperature recorder: Definition and usefulness

A temperature recorder, sometimes called a data logger, is a stand-alone electronic device designed to monitor, measure and record temperature variations in a given environment. Used in the cold chain, food processing, pharmaceutical laboratories, logistics or mass catering, it ensures compliance with HACCP, ISO or EN12830 standards.

These systems are essential for preventing health risks, guaranteeing the quality of perishable products, and documenting proof of control in the event of an audit or health inspection.

Why use a temperature recorder in 2025?

Using a temperature logger enables continuous automated monitoring of thermal conditions in your equipment or sensitive environments. By creating time-stamped reports in PDF format, you can easily meet the requirements of quality audits. It also significantly reduces losses due to cold chain breakdowns, by quickly detecting deviations. By guaranteeing regulatory compliance with HACCP, ISO or EN12830 standards, these devices become a real decision-making tool, providing usable, archivable and easy-to-interpret data.

The main types of temperature recorder

 USB recorder (stick type or mini-datalogger)

• Simple, economical and autonomous
• Automatically generates PDF reports
• Ideal for occasional transport, cold storage, etc.

 Wi-Fi or Cloud recorder

• Data transmitted in real time via the Internet
• Automatic alerts (email/SMS) in case of deviation
• Suitable for multi-site networks or continuous monitoring

 Multichannel recorder with external probes

• Simultaneous monitoring of several zones or enclosures
• Used in commercial kitchens, industrial refrigerators or storage rooms

 High-temperature recorder (core)

• Designed for low-temperature cooking or pasteurization
• Withstands temperatures up to 150°C and over

How to choose the right temperature recorder?

Here are the essential criteria for making the right choice:

• Measurement accuracy: ±0.3°C or better for critical environments
• Temperature range: -80 °C to +150 °C as required
• Autonomy: up to 2 years in normal use
• Connection: USB, Wi-Fi, Bluetooth, 4G or cloud integration
• Certification: EN12830 (mandatory for cold chain applications)
• Software or interface: automatic PDF reports, secure cloud, Excel export

Temperature data loggers: fields of application

•  Agri-food & mass catering: monitoring of cold chambers, re-tempering, HACCP monitoring
•  Laboratories & pharmaceuticals: sanitary compliance for vaccines, biological samples
•  Logistics and transport: container monitoring, refrigerated vehicles, delivery traceability
•  Industry: temperature control on production lines

FAQ : Temperature data loggers - Frequently asked questions

What is the recommended recording frequency?
Every 5 to 15 minutes, depending on the level of criticality. Less for statistical data, more for sensitive products.

Are all recorders certified?
No. For cold chain, check EN12830 compliance.

Do I need to calibrate the device regularly?
Yes, annual calibration is recommended, especially in regulated environments.

Can I monitor several cold storage units with a single device?
Yes, with a multi-channel model or a station with external probes.

Does a Wi-Fi recorder work without Internet?
It stores data locally and transmits them as soon as a connection is re-established.
